Introduction: Life Lamp

Picture of Life Lamp

I made a Tshirt for people threatened by a heart attack, called Life lamp.

When the patient is suffering a heart attack, they will have the following signs:

  • Chest discomfort;
  • Discomfort in other areas of the upper body;
  • Shortness of breath;
  • Others like dizziness, fatigue, lightheadedness, clammy skin, cold sweat, etc.

Therefore, it is hard for them to cry for help. The patients have a common gesture when they are under attack: pressing their chest hard. For Life Lamp, the lamp is attached to the Tshirt. When the victim is suffering a heart attack and press their chest unconsciously, the light will be on. People around this patient will be notified and can help him/her.

Step 1: Upload Code to ATtiny Using Arduino

Materials:

  • Arduino
  • ATtiny
  • Wires
  • 10uf Capacitor

int ledpin = 1;
int sensorpin = A1; int sensorValue = 0; void setup() { pinMode(ledpin, OUTPUT); pinMode(sensorpin, INPUT); } void loop() { sensorValue = analogRead(sensorpin); if(sensorValue>800 ){ digitalWrite(ledpin,HIGH); delay(500); digitalWrite(ledpin,LOW); delay(500); } }

Step 2: Testing the Circuit

Material:

  • Arduino
  • Led
  • ATtiny
  • 10kΩ resistor
  • Velostat
const int ledPin = 3;
const int flexPin = A0;
int value; 

void setup(){
  pinMode(ledPin, OUTPUT); 
  Serial.begin(9600);
}
void loop(){
  value = analogRead(flexPin); 
  Serial.println(value); 
  delay(100);                     
}

Step 3: Making a More Sensitive Pressure Sensor

Materials Needed:

  • Velostat
  • Conductive Fabric
  • Insulated Fabric
  • Thread

The middle layer is a piece of Velostat. The two outer layers are made of normal insulated fabric. Putting conductive strips on the outer layer makes it less resistive when being pressed. Then stitch them together and make sure the layers not close to each other in a normal state.

Step 4: Designing and Building the Circuit on a Piece of Fabric

  1. Draw a circuit with water erasable pen
  2. Build the circuit with conductive thread
  3. Put some cotton to make the light diffuse

Step 5: Attaching the Circuit to the Clothes

A system like this could really save lives. I hope that something like this gets developed commercially.
